The end of the Cold War was accompanied by the idea that the fall of the Berlin Wall represented the beginning of the unification of Europe. Mikhail Gorbachev talked in terms of a “Common European Home,” an idea that continues in the guise of the project for a “Greater Europe.” However, right from the start, the transformative idea of Greater Europe was countered by the notion of “Europe whole and free,” whose fundamental dynamic was the enlargement of the existing West European order to encompass the rest of the continent. This was a program for the enlargement of the Atlantic system. After some prevarication, the enlargement agenda proved unacceptable to Moscow, and while it continues to argue in favor of transformation its main efforts are now devoted to creating some sort of “greater Eurasia.” There remains a fundamental tension between Atlanticist and pan-continental version of the post-–Cold War international order in the region. This tension gave rise to conflict and war: in 2008 (the Russo-Georgian War) and again from 2014 (Ukraine), and to what some call the Second Cold War. The continent is once again divided. However, pan-continentalism is far from dead, and although Greater Eurasian ideas have thrived, some sort of Greater European continentalism remains on the agenda. Is this, though, no more than a “sad delusion” or a genuine possibility?
